Making the world’s information safely accessible.

Safety First

Keeping over three billion devices safer.

Google Safe Browsing helps protect over three billion devices every day by showing
warnings to users when they attempt to navigate to dangerous sites or download
dangerous files. Safe Browsing also notifies webmasters when their websites are
compromised by malicious actors and helps them diagnose and resolve the problem so
that their visitors stay safer. Safe Browsing protections work across Google
products and power safer browsing experiences across the Internet.

Our Transparency Report includes details on the threats that Safe Browsing
identifies. The Transparency Report includes our Site Status diagnostic tool that you can use to see whether a site
currently contains content that Safe Browsing has determined to be dangerous.

Beginnings

A history of safety

Safe Browsing launched in 2007 to protect users across the web from phishing
attacks, and has evolved to give users tools to help protect themselves from
web-based threats like malware, unwanted software, and social engineering across
desktop and mobile platforms.

Our Safe Browsing engineering, product, and operations teams work at the forefront
of security research and technology to build systems that help users protect
themselves from harm. Check out our Research and the
Google Security Blog
for updates on Safe Browsing and other Google security technology.

API Documentation

Protection for all

To make the Internet safer for everyone, we’ve made Safe Browsing services free and
publicly available for developers and other companies to use in their applications
and browsers. Today, half the world’s online population is protected by Safe
Browsing. If you are a developer and would like to protect your users from online
threats, get started by visiting our API
Documentation. If you are a webmaster, you can sign up for
Google Search Console to receive notifications and help with security issues.

Policies

Safe Browsing gives users the ability to protect themselves from multiple types of
unsafe sites and applications. Our policies help define the types of web threats
about which Safe Browsing will notify users and webmasters.

Malware

Since 2006, Safe Browsing has warned users when they attempt to navigate to
sites that might be malicious. Malware is software specifically designed to
harm a device, the software it's running, or its users.

Unwanted Software

In 2014, we added protection against a broad category of harmful technology
that we now call “Unwanted Software”: for example, programs disguised as
helpful downloads that actually make unexpected changes to your computer like
switching your homepage or other browser settings to ones you don’t want.

Social Engineering

Since 2005, Safe Browsing has protected users across the web from Social
Engineering attacks. A Social Engineering attack tricks users into performing
an action that they normally would not if they knew the true identity of the
attacker. A common example is Phishing, where a page tries to steal a user's
password or other personal data.
